What are macronutrients? Macronutrients are substances that the body needs for growth, repair and replacement of cells and cell parts. They are defined as a class of chemical compounds. There are three types of macronutrients, i.e., protein, fat and carbohydrates. Each of these three substances provide the body with calories and/or energy. Watching the amount of intake of each of these substances is critical to being able to maintain a healthy body but elimination of them from a person’s diet can be just as devastating so it’s important to understand them and consume them in healthy amounts. Now let’s look at the macronutrients more closely.
